In depth Review of Casio MTG 900 Shock Waveceptor Tough Solar Watch

HERE IS THE MANUAL

if you dry the watch out completely and the battery is good it might work again. when the battery is removed there is often a couple of pins you need to short out before the watch will work

Theoretically means it will resist water penetration to 50 meters. Approx 150 feet deep.
I would not test that limit, but you should be fine in a pool or shower etc..

This watch is made by Casio. Look here for more information please: http://www.casio.com/products/Timepiece/G-Shock/

Thank you

mcdevito 75 here, Usually 50--100 meters of water resistance on brand new watches. However after a battery change, unless you also change the gasket (rubber ring) on the cover, you could loose all water resistance capability.

"Water resistant 5 bar" means that it is water resistant to and depth of 50 meters. (1 bar is approximately equal to 10 meters of water depth).

You definetely CAN NOT dive with this watch. It is good for swimming and snorkeling only. Real divers watches withstand at least 200 meters of depths and are specialy designed for it.
One of the best affordable divers watch manufacturers novadays is Seiko. Check Seiko website and learn about divers watches and all the features they have. List of waterproof markings and explanations are also available.
